Who is the moron with the 45 bitcoin wall? Does he realize hes devaluing his own coins just to pick up a few BC? The community is patient for an eventual price swell but its moves like these that discourage new miners. Price increases will make new miners want to join and thus make adoption happen even sooner. Lets try to get more miners to punish them for this kind of thing. Day-trading this coin only slows that process.
It is most likely multiple people. If two or more people place the same sell order, Mintpal combines them together. So if I have a sell order for 10BTC @ 40000 and you have a sell order for 10BTC @ 40000 it will be displayed as 20BTC @ 40000.
This puppy whale just want to buy your cheap Blackcoins, this pile of garbage needs to be wiped out faster, I already suggested some weeks ago to create a superbuy the pool, it would be perfect to break off these walls.

Do you want a recipe for success on blackcoin ? Then implement now (poolsuperbuy + blackshild ) it will end with this shit.
By the love of god stop putting large sale walls, stagger your sales to have higher profitability and a smoother output....
I think your idea is good and I suggested something like this before. We could implement this tactic without the pool. Everyone interested can either mine for a week on other pools and pledge to buy on a certain day at a certain time on Mintpal. If you are not a miner just buy at the specific time and date set. People would have to pledge to buy at the current market price(not wait for a dip) and not to sell for at least 3 days after buying. If a large percentage of this community joined in the outcome would be epic
...I am in if anyone else is interested....
